voltage across C, current through C, and SCR,, and
voltage across SCR, indicating that voltage across
the SCR change polarity during turn off time. That is
the reason that in this application SSGD uses only
voltage across SCRs to restore charge at storage
capacitor and storage capacitor current is low. In this
case, only diode D, is stressed by snubber discharge
current .
To observe ability of storage capacitor to restore the
charge for different firing angles, percentage used
time of turn off time, when it is possible to restore the
